00 Dead-band generation is bypassed for both output signals. In this mode, both the EPWMxAand EPWMxB output signals from the action-qualifier are passed directly to the PWM-chopper submodule. In this mode, the POLSEL and IN_MODE bits have no effect.
01 Disable rising-edge delay. The EPWMxA signal from the action-qualifier is passed straight
through to the EPWMxA input of the PWM-chopper submodule.
The falling-edge delayed signal is seen on output EPWMxB. The input signal for the delay is
determined by DBCTL[IN_MODE].
10 The rising-edge delayed signal is seen on output EPWMxA. The input signal for the delay is
determined by DBCTL[IN_MODE].
Disable falling-edge delay. The EPWMxB signal from the action-qualifier is passed straight
through to the EPWMxB input of the PWM-chopper submodule.
11 Dead-band is fully enabled for both rising-edge delay on output EPWMxA and falling-edge
delay on output EPWMxB. The input signal for the delay is determined by DBCTL[IN_MODE].
